Issue regarding image generation

When I create an image with my assistant, the download fails. Instead of an image, it only downloads a text file. I am attaching such a file for your reference.

Steps to reproduce:
1. Ask seedy.wordseed.de to generate an image

2. Click on the little download button

3. Check the downloaded file

The same happens when I am doing a right-click and select “Save image”, it downloads the same file.

This happens on Mac + Chrome as well as on iPad and Windows PC.

A few of my clients reported this issue.
